Price Hunter
Find the best price for any product across multiple e-commerce platforms.
Quick Start
Input: Product name, model number, or product URL
Output: Structured price comparison table with: - Platform name - Price (normalized to user's currency) - Seller rating (when available) - Shipping cost estimate - Direct link
Workflow
Step 1: Clarify the Product
Before searching, confirm: - Exact product name/model (e.g., "Sony WH-1000XM5" not just "Sony headphones") - Preferred currency (default: USD) - Region preference (default: global) - Any specific requirements (new/used, prime shipping, etc.)
If the user provides a URL, extract the product identity first.
Step 2: Multi-Platform Search
Search these platforms based on relevance:
International: - Amazon (amazon.com, regional sites) - eBay - AliExpress - Temu - Walmart
China:
- JD.com (京东) - 京东自营价格较准
- Taobao (淘宝) - 搜索 "{商品名}" site:taobao.com 价格
- Tmall (天猫) - 官方旗舰店,搜索 "{商品名}" site:tmall.com
- Pinduoduo (拼多多) - 搜索 "{商品名}" 拼多多 价格 或 百亿补贴
Platform notes:
- 拼多多:
- ⚠️ 无法提供直接商品链接(网页版需登录,搜索引擎无法抓取)
- 价格来源:第三方聚合站(值值值、什么值得买等)
- 输出格式:提供价格 + 建议用户在拼多多APP内搜索
- 示例:拼多多 - ¥329 - *请在APP内搜索"Keychron K3 Pro"*
- 淘宝/天猫: 部分页面需要登录,优先用搜索结果的摘要信息
- 京东: 价格相对透明,容易抓取
Region-specific (ask if needed): - Rakuten (Japan) - Coupang (Korea) - Shopee (Southeast Asia)
Use web_search with queries like:
- "{product name}" price Amazon
- "{product name}" site:ebay.com
- "{商品名}" 京东 价格
- "{商品名}" 拼多多 百亿补贴
Step 3: Extract Price Data
For each promising result:
1. Use web_fetch to get the product page
2. Extract: price, seller, rating, shipping info
3. Note any coupons or discounts mentioned
Price extraction tips:
- Look for ¥, $, €, £ symbols
- Check for "from" prices (indicates multiple variants)
- Note if price includes tax/shipping
Step 4: Normalize and Compare
IMPORTANT: Output format depends on platform:
For Discord/WhatsApp (no tables): Use bullet list with inline links:
**🏆 最划算**
• **Amazon** - $279 - Amazon官方 - 4.8★ - 购买
• **eBay** - $265 - topSeller99 - 4.9★ - 购买
• **AliExpress** - $198 - Official Store - 4.7★ - 购买
For other platforms (support tables): | Platform | Price | Seller | Rating | Shipping | Link | |----------|-------|--------|--------|----------|------| | Amazon | $279 | Amazon | 4.8★ | Free | 购买 |
Link requirements:
- Every result MUST include a direct clickable link when available
- Use markdown format: 购买 or Buy
- Exceptions:
- 拼多多: Cannot provide direct links. Output format: 拼多多 - ¥329 - *请在APP内搜索"商品名"*
- 淘宝/天猫: Use search result links when product pages require login
- If multiple sellers exist, link to the best-priced one
- Verify links are accessible (not blocked by login wall)
Currency conversion: Use approximate rates if needed (no need for API)
Step 5: Recommendation
Provide a clear recommendation: - Best value: [Platform] at [Price] - [Why] - Fastest delivery: [Platform] - [Shipping time] - Most reliable: [Platform] - [Seller reputation]
Tips
- For electronics, check if the price is for the correct region/version
